So it was a nice surprise when I first donned the Blueyes Chill and they slid nicely between head and liner. It turns out that all Blueyes shades are designed with the helmeted or un-helmeted motorcycle rider in mind. The Chill comes in both a grey for color neutrality, or a bronze (the one I got) for increased contrast while reducing glare. My eyes are really sensitive to glare, so I was very thankful for this feature. Blueyes shades are also polarized, which makes for less eye fatigue (most good sports shades have this). However if you have any sort of polarization in your helmet's faceshield (like on a Pinlock insert) it will make for a psychedelic display of rainbow colors. I liked it, but I'm aware most people aren't into that sort of thing.
